AUTOMATIC OPTICAL INSPECTION SERVICES

Automated optical inspection (AOI) is an automated visual inspection of printed circuit board (PCBA)Assembly where a camera autonomously scans the device under test for both catastrophic failure (e.g. missing component) and quality defects (e.g. fillet size or shape or component skew). It is commonly used in the manufacturing process because it is a non-contact test method. It is implemented at solder paste inspection (SPI), post-reflow and pre wave.
